초록

국내에 유통되는 자동차용휘발유의 산소함량은 2.3 wt % 이하로 규제하고 있는 반면, 유럽 및 세계연료헌장(WWFC)에서는 2.7 wt % 이하로 규제하고 있다. 산소함량을 결정짓는 함산소물질은 내연기관 내에서 연료의 연소를 보조하여 옥탄가를 상승시키고, 불완전연소로 야기되는 CO, HC와 같은 배출가스 저감에 효과가 있는 것으로 보고되고 있다. 2000년대 이전 미국, 유럽 등에서 자동차용휘발유의 산소함량 변화에 따른 차량적용 평가연구가 추진된 바 있으나, 발전하고 있는 연료품질, 자동차기술현황을 반영한 국내실정의 연구는 많지 않다. 본 연구에서는 자동차용휘발유의 산소함량을 변화시킨 3종의 연료를 GDI, MPI 연료 분사 방식의 차량에 적용하여 비교 평가 하였다. 결과적으로 산소함량 변화에 따른 연비, 배출가스의 변화는 유사하였지만, GDI 엔진에서 산소함량이 증가할수록 PN은 감소하는 경향을 나타내었다.

While the oxygen content of gasoline for automobiles in Korea is regulated to less than 2.3 weight %, European and World-Wide Fuel Charter (WWFC) regulate it to less than 2.7 weight %. The oxygen content of oxygen-containing materials increases the octane number of the fuel due to the secondary combustion in the internal combustion engine. It has been reported to be effective in reducing emissions, such as CO, HC, which is caused by incomplete combustion. Before 2000s in the United States and Europe, there has been many researches about vehicle application of the changes in oxygen content of gasoline. However, there are not many domestic researches which reflect the improvement of the fuel quality and automotive technology. In this study, fuels of three different oxygen contents were applied to GDI and MPI engines. As a result, the changes of fuel consumption and emission gas were very similar depends of the oxygen content changes. The PN in GDI engine was decreased as the oxygen content was increased.
